SANITARY ROTATING DIAPHRAGM FOR TELEFHONES...

SPECIFICATION forming part of Letters Patent No. 776,112, dated November 29, 1904. Application filed May 7, 1904:. Serial No. 206,879. (No model.)

To all whom it may concern:

Be it known that I, SIDNEY CHURGHILL-OT- TON, commercial traveler, a British subject,

residing at 206 Albert street, East Melbourne, in the State of Victoria, in the Commonwealth of Australia, have invented a certain new and useful Invention in Sanitary Rotating Diaphragms for Telephones, of which the following is a specification;

This invention is designed for the purpose of allowing a person using a telephone to mechanically move away the previously-used paper diaphragm hereinafter described, when a fresh surface will be presented, so that there will be a clean diaphragm for each person to breathe or speak upon.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 represents an elevation of a telephone-trans mitter with my said diaphragm attachment thereon shown in section upon line (a?) of Fig. 2, such figure representing a plan of the attachment. Fig. 3 'is a section elevation of same, taken upon vertical line 0 (Z of said Fig. 2.

In carrying out my said invention I use, preferably, a square-shaped plate A, having a central circular opening B and two partiallyflanged sides C and flanged ends 1) and E, while mid-length of the latter are situated two cars or lugs F F, which both serve the purpose of allowing the said attachment to be suitably and securely fixed upon the transmitter by means of wire or the like. With said flanges U of plate A are arranged three rollers, one of which, G, called the removable feed-roller carries a continuous roll of sanitary paper H, which is mechanically unwound to form a band 1, such band moving upward through the slot J and over the central opening B of plate A, thence passing downward through the slot K and outward between the two rollers L and M, termed the tension-rollers, from which the free end portion of the paper band hangs ready to be cut or torn oif by pressing it against the bottom edge 0 of the end E. Said feed-roller G is carried by the spindle P, one end of which has a removable pin forming its axle Q, which allows of the said roller G being removed and replaced, carrying another supply of paper when required. The said continuous roll I-I may be marked off into sections by black lines or perforations, such as It.

For the purpose of insuring the continuous feed of the paper band 1 to and across the transmitter-mouthpiece S, I connect the paper-feed roller G with one of the said tensionrollers by means of a small chain or band T, and uponone end of the spindle P of said roller M is secured a small milled wheel or disk U, which is situated at the outer side portion ofsaid plate A.

It may be explained that the rollers G, L, and M are arranged beneath the said flanged plate A and that the paper-band diaphragm traverses above. The di'lferent parts may be made of vulcanite, zylonite, or any suitable material.

The manner of using my said invention is as follows: In order-to discard the previouslyused paper-band diaphragm and to have a clean and unused one, the user operates the milled wheel or disk U of the said tension-rollers L and M, which operate the chain T and feedroller G, thus moving the paper band 1 mechanically across the central opening B of the plate A and also mechanically moving away the previously-used paper-diaphragm surface that is to be torn oil or cut off, as before de scribed.

Having now described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a telephone-transmitter, of a frame having a central opening secured thereto, a roll G carrying the paper diaphragm mounted in one side of the frame, rollers for feeding the paper mounted in the other side of the frame, and a chain connecting the roll G with one of the other rollers, substantially as described.

2. As a mechanically hand-operating dia phragm attachment to and for telephonetransmitters for carrying and feeding a roll of paper serving as a consecutive series of paper diaphragms, the combination of aplate or frame with central opening and flanged In witness whereof I have hereunto set my sidehs 1and ends suitalily slottecll and provided hand in presence of two Witnesses.

Wit ugs, aremovab efeed-ro ler with thumb w r screw or disk, two tension-rollers and chain SIDNEY (JHURCHILL'OETON' connecting such feed-roller with one of such WVitnesses:

tension-rollers adjusted and operating as be- JONATHAN BEAR,
